text: The beta 2,6 linkages of levan allow for it to be soluble in both water and oil; however, the water temperature varies the degree of solubility. Levan also is insoluble in many organic solvents such as methanol, ethanol, and isopropanol. The branching of levan allows it to have a high tensile and cohesive strength, while the hydroxyl groups contribute to adhesion with other molecules. The intrinsic viscosity n, a measure of the substance effect on viscosity of a solution, tends to be very low for levan. This allows levan to be utilized in a pharmaceutical setting.
